Acid and water-based stained concrete floors

  • Acid stain

    Acid stain reacts with the concrete, so the color forms inside the slab and is essentially permanent. It suits a floor you plan to keep one color.

  • Water-based stain

    Water-based stain sits on the surface, so you can go lighter, darker or a new color later. It suits a room you think you'll want to change down the road.

Is stained concrete right for my floor in Martinez?

Stained concrete flooring in Martinez colors the concrete slab you already have, so a plain gray floor becomes a finished one without laying anything on top of it. Acid stain does it by reacting with the concrete to make color inside the slab, and most of the job is getting the surface ready first.

Most of the calls I get are for a gray slab in a basement, garage, shop or living room, often one that just had carpet or tile pulled up. The price moves with the size of the floor, what's covering it now, how many cracks there are, how much old sealer needs stripping and removal and which stain you pick. The schedule mostly turns on that same prep, because all of it gets done before any color goes down. I put your floor's numbers in a written estimate after I've seen it.

Cleaning, patching, staining and sealing your concrete

I look at the slab and how you'll use the room first. If it's too rough for stain, I'll say so, and we can talk about terrazzo flooring or basement flooring options instead.

  • Clean and strip old sealer

    Stain shows every flaw, so we clean the slab and strip any old sealer before color goes on, which keeps the finish even.

  • Patch cracks and scuffs

    We repair cracks and scuffs ahead of the stain, because stain soaks in and makes every mark on the slab stand out.

  • Pick the right stain

    We help you choose acid or water-based stain, depending on whether you think you'll want a different color later.

  • Stain and seal

    Our crew applies the stain you picked evenly across the floor, then finishes it with a sealer over the color.

Why Martinez owners call Stonefield for stained floors

I taught myself floor coatings on my own garage, learned the rest beside experienced crews and started this business in Martinez in 2017. What I care about most is what's under the color, so we put our time into prep and tell you what we'll do before you sign.

Stained concrete questions from Martinez owners

How much do stained concrete floors cost in Martinez?

Stained concrete floors across the US usually cost about $2 to $28 per square foot, and that's the national market range, not our price. It's a wide spread because every slab starts out different, so a national figure won't tell you much about yours. Your Martinez number comes from the written estimate I give you after I look at the floor.

How long does a stained concrete floor last?

With proper care, a stained concrete floor easily lasts 20 years or more. Most of that care is keeping the sealer up, since the sealer is what takes the daily wear.

How often should you reseal a stained concrete floor?

Plan on resealing every two to four years, because the sealer is what protects the floor from moisture, scratches and daily wear. If your floor looks dull or scuffed sooner, call us about concrete sealing and I'll come take a look.

How do I know if my concrete is ready to stain?

One acid stain maker says the concrete should be at least four weeks old and free of all debris before it's stained. To check for moisture, that maker has you tape plastic over one square foot of floor and pull it up the next day, and if the floor underneath is wet, it says the floor shouldn't be stained and sealed. That's worth knowing if you've got a new slab or a damp basement.

Can you stain concrete that's under old carpet or tile?

Usually, yes, once the old flooring comes up and the concrete underneath is ground and cleaned. That removal and grinding adds labor, so it raises the price compared with a slab that's already bare.

Can a concrete floor that was stained before be restained a different color?

It can, but a new stain over a floor that was stained before may not give you the color you expect. I'd rather see the floor and talk through what's on it now than pick a color off a sample and hope.

Stained concrete flooring in Martinez and nearby cities

In Martinez, the city's Building Department issues building permits to homeowners and licensed contractors for work inside city limits, so check with them before you assume a staining job doesn't need one. If yours does, we'll sort out with you which city or county office covers your address and who pulls it, and we work with that office from there. The city also lists a business license as required for contractors, which is worth asking about when you compare bids.

We're based in Martinez and take jobs in the cities around it in Contra Costa and Solano counties. A lot of the slabs we uncover here have old glue, paint or patches on them, the same as on jobs in Concord and Pleasant Hill, and that's usually what sets the prep.
